AUTOMATIC GAS-LIGHTER.

To'oll whom c't may concern:

'Be it known that I, JOSEPH C. LANDES, a citizen of the United States,residing at ol'legeville, in the county of Montgomery, 1i State of.Pennsylvania, have invented a new nndiiseful Automatic Gas-Lighter, ofwhich the following is a specification. My invention consists of animprovement in automatic gas lighters similar to the forms shown in myseveralapplications for Letters Patent, filed by me on the 15th day ofNovember, 1906, Serial Number 343,481, and February 15, 1907, SerialNumber 357,499, also February 23, 1907, Serial N urnher 358,765, theob'ect being to automatically light the burner y the movement of themovable arts, and to automatically extinguish the same with lessvariation, or increased gas pressure in the gas mains. B this presentimprovement there is practieally ,no additional resistance offered thefloat in operating the gas valve, the filament, theclosin of electrodes,or the regulator, all of them being normally float and practically noadditional resistance oil'e'red to move them to a perfect 0 eration. Inmy former applications above re erred to the resistance .to the floatlsincreased when the float is actuated and therefore requiring a greaterpressure 0 operate, over the present application. I attain these objectsby the mechanism illustrated in the accompanyi drawing in which igure 1.reprsents a side elevation of a dyingmy invention.

gas chamber 34, also alibi-(ling space for cross bar 7 connectingrods 1) and 17.

11 rcprcsmits a cup for weight to hold the float (4) down under normalgas pressure.

20 represents a gas valve, closed by cap 19 dipping into mercury orolhcr scaling solution 18, the same lacing actuated by the movement offlout 4 through connecting rods 9 and 17 and cross bar 7.

14* represents an electrode chamber confrom float at 12.

Suitably connected to casing 2 is a regulating device adapted toregulate the move ment of float 4.

When lighting is desired, the pressure in the gas mains is increased,causing the float 4 and pin 26 in rod 27 to move upward to the limit at30 of the regulating device, 26 being a pin at right angles with rod 27pas ing along the outer edge (or right side) of cam 28 to limit at 30with the first upward movement of float 4 at which point. the cap 19being lifted from the mercury or other sealing solution 18.in valve 20permitting a flow of gas to pass to the burner 22, at this pointelectrode chamber ll being clcvalcd suflicicntly to cause elcclrodo 15to dip lulu electrode. 13 and closing an electrical connccti on withbattery 16 through lilmncnt 1-3 3. causing it to glow and ignite the gascoir vcyed to it by tube 24. The features of the filament itself do notionnlhc subject lllill; tor of any claim of invention, they being" oldin the art. Tube 24 being hinged to filament case 23' so as to adjustitself in space between the-burner 22 and filament case 23' when thefloat 4 is lowered fl'Oil'l the burner. When the lights are to beextinguished the pressure is again increased carrying pin 26 with float4. to point at 31 after which the pressure is reduced to normal andfloat 4 7 and pin 26 returning through channel 32 t0 gluce of beginning,cam 28 moving forwar affording room for pin 26 to pass through andclosing thereafter when pin 26 and float 4 are again in position forighting.

l'he elevation at 31 being less than 30, electrodes 13 and 15 do notconnect, and the electrical connection is not formed with the batteryuntil pin 26 is again carried to limit at 30 for lighting,

The operation is as follows, the parts being in position as seen in Fig.1: An increased gas pressure placed in the gas mains causes the float tto move upward carrying cap 19 (in valve 20) upward and permitting thegas to flow to the burner 22, at which time the same n )Wtll'tl movementof float 4 carryin r electrode chamber 14 and causing clertrot e 13 and15 to close a circuit of battery 16 through filament 23 which is made toglow and ignite the gas conveyed to it through tube 24. The pressurethen being reduced to normal in the gas mains, float 4 with rod 27 andpin 26 returns, thus bringing the pin 26 to point 29. Thepartsare thussulficiently lowered to disconnect the battery circuit at. 13 and 1.":but cap 19 still remains above seal 18 and gas will continue to flow tothe burner and lights will continue to burn. An increased gaspressure inthe gas niains causes the float L to move upward. .\s the float rises,the cap 19 is raised with the same due to the rod 9, cross-liar 7 androd 17, the latter being attached to the float. Said cap is thus removedfrom the seal 18. while the light is burning, and retained in saidposition owing to the pin 26 having passed the cam 28. Then owing to theweight 33 on the rod or lever 27. said pin abuts against. the sto J 30,and so limits the ascent of the cap. i Vhen the pressure of gas isnormal, the pin drops upon the top 29 of the cam limited in its movementto the left by the lip 28*. \Vhen the light is to be extinguished thepressure is increased, then the pin rises to greater extent and thenturns to the ct' and over said lip, it abutting; against the part 31 as.a stop. Then the pressure is dis-reused, when the pin rifles down thepassage or channel 32 and returns to its first position. The stop30 ishigher than the stop 31, whereby when the float is at its highest.point, the clectrode13 contacts with the electrode [5, thus completing acircuit. When the pressure is relieved, the electrode 13 lowers, aiulthe circuit is'brokcn, and remains so until further operation of thedevice.

Having thus described my invention what. I claim as new and desire tosecure by Letters Patent, is:

1. In a device of the character described the combination of a casing,a. float adapted to be actuated by the pressure of gas, a burner, astationary contact piece supported thereby, a movable contact chambercarried by said float, a sealing valve controlling the How of gas to theburner, and means in suitable connection with said valve and said floatwhereby said valve is actuated b the movement of said float and meansfor imitin the upward movement of the valve.

2. In a device of the character described, the combination of a casing,a float adapted to be actuated by the pressure of gas, a burner, astationary contact iece supported thereby, a movable contact c ambercarried thereby, a sealing valve controlling thefiow of gas to theburner, means connected with said valve and said float for opening saidvalve upon one upward movement of the float, and for closing said valveon the next upward and return movement of said float to normal position.

3. In a device of the character described the combination of a casing,a, float adapted to be actuated by an increased pressure, a. burner, astationary contact iece support-ed thereby, a movable contact c ambercarried thereby, a battery in suitable connection with said movable andsaid stationary con: tact pieces, a filament with a tube attached saidfilament being located on said float, and carried thereby in circuitwith contact chamber.
